A proof can validate a block; it cannot choose who gets to build it

Starknet turned StarkWare’s proof machinery into a shared Cairo network, then gave STRK three operational jobs: paying fees, staking and voting. Each job is now real, but none proves the decentralization story complete. The sharpest way to read Starknet is to follow the gap between mathematical validity and the human or institutional authority that still orders, proves and upgrades the system.

StarkEx proved the machinery before Starknet opened the city

StarkWare’s first production route was StarkEx, live from June 2020. It let a specific exchange or application send batches to a StarkWare service, generate a STARK proof and settle a commitment on Ethereum. Rollup, Validium and Volition deployments could make different data-availability tradeoffs, and the application retained its own operator.

Starknet reused Cairo, SHARP and STARK verification for a different social object: a shared network where unrelated developers can deploy contracts without asking a customer operator. That difference explains why StarkEx users could receive Provisions without their old application becoming governed by STRK.

The shared network still divides execution from settlement. A sequencer chooses and runs transactions; SNOS and the prover produce verifiable evidence; Ethereum accepts the resulting state update. Validity limits fraudulent state, while ordering and availability remain operational questions.

STRK acquired its functions in public, one at a time

StarkWare created ten billion units in May 2022 and minted them on Ethereum on November 30, before public trading. The February 20, 2024 Provisions round made more than 700 million claimable to a broad eligibility set. A September 2024 onchain vote approved the minting curve, staking v1 launched November 26, and v0.14.0 made STRK the sole fee currency in September 2025.

The sequence matters because the token’s three labels are not interchangeable. Fees purchase execution; staking locks assets behind validator performance and a seven-day exit delay; governance assigns proposal votes. None gives a passive right to sequencer income, ownership of the code company, or repayment from the Foundation.

A revised unlock softened the cliff without erasing concentration

The original ten-billion allocation put 38.21% with early contributors and investors, 10.76% with StarkWare, and the remaining 51.03% across grants, provisions, rebates, reserves, treasury and donations. Foundation-retained tokens can be contractually unlocked without being counted as circulating until moved into programs.

After criticism of the initial cliff, the current schedule capped releases at up to 64 million per month from April 2024 through March 2025, then up to 127 million per month through March 2027. Locked units cannot be sold, transferred or pledged, although voting delegation is allowed; the token document says staking locked units was not allowed at its last update.

Unlocking and inflation are different supply channels. Unlocks make existing units transferable; the staking curve creates new units. The 2025 review reported 33 million STRK inflation since staking began, while the token document reserves later block-reward minting for the stage when StarkWare is no longer the sole sequencer operator.

Attestation measures validators before handing them the keys

Staking v1 initially accumulated economic weight without consensus duties. Phase 2 added epochs and assigned each validator a block to attest. Missing the window costs rewards, so delegators can observe reliability, but the attestation does not let that validator propose the block it signs.

Starknet v0.14.0 introduced distributed sequencing components, and S-two replaced Stone as the mainnet prover in November 2025. Official materials still speak of open block production and decentralized proving in future tense. The network has multiple moving parts, yet a permissionless sequencer-prover market is not established by phase-2 staking alone.

Token votes share the upgrade path with a privileged council

STRK voting has approved real changes, beginning with the staking mint curve. Under the 2026 process, major and minor releases both face community votes, though their delays and Council involvement differ. The Foundation’s ability to allocate and redelegate large voting blocs means participation is open but influence follows token distribution.

The 12-member Security Council sits on a separate rail. It vets major security changes and can act immediately with 75% approval during an emergency. L2BEAT’s independent analysis also notes that Council signers form part of Starknet’s fallback proving and liveness assumptions. The Council is a disclosed safety mechanism and a concentrated control surface at the same time.

The unfinished work is operational, not cryptographic

A STARK proof answers whether a claimed execution follows the rules. Starknet’s remaining decentralization work asks who supplies those rules, transactions and proofs when a favored operator disappears or refuses service. STRK gives holders tools to influence that answer, but its legal disclaimers, delegated concentration and emergency path keep governance rights narrower than ownership.

Evidence and primary sources

What is Starknet?

Starknet is a shared Layer 2 where developers permissionlessly deploy composable Cairo contracts. A sequencer orders and executes transactions, state differences are published for Ethereum data availability, and recursive STARK proofs let Ethereum verify state transitions without rerunning them. Every Starknet account is a smart contract, so authorization and batching can be programmed at account level.

StarkEx is an ancestor and sibling product, not another name for Starknet. StarkWare began operating StarkEx in June 2020 as a customized service for individual exchanges and applications; each deployment has its own operator and data-availability choice. Starknet Alpha opened a general-purpose network in 2021. Some early STRK recipients were StarkEx users, but holding STRK does not govern a StarkEx operator or grant rights in its customer deployments.

What problem does Starknet solve?

STARK proofs can prevent an invalid state transition from settling, yet proofs do not automatically decide which valid transactions enter a block, who runs the prover, or who may replace core code. Starknet’s history is therefore a move from cryptographic validity toward operational decentralization. The distinction matters whenever “secured by Ethereum” is read as if it also guaranteed censorship-free sequencing and immutable administration.

By late 2025, v0.14.0 had introduced a distributed sequencer architecture and S-two had replaced Stone for mainnet proving. Staking v2 validators attest assigned blocks and lose rewards when they fail, but current documents still describe block production, validation and permissionless proving as later phases. The working system is further along than a single-sequencer prototype and short of its proposed fully permissionless operator set.

How does Starknet work?

Since Starknet v0.14.0 on 2025-09-01, transaction fees can be paid only in STRK. The receiving sequencer may convert part of those fees to ETH because Ethereum settlement gas is denominated in ETH. A token balance therefore buys execution when submitted with a valid account transaction; it does not promise fee revenue to every holder.

Staking is live in phase 2. A validator stakes at least 20,000 STRK and runs a full node. Each epoch, a recurring protocol period, assigns the validator one block; an attest transaction containing its hash must arrive within the prescribed submission window. This publicly demonstrates that the validator is tracking the network. Missing the submission forfeits all rewards for that epoch. Delegators may contribute any amount to an accepting validator and share rewards without performing validator duties, so the chosen validator’s performance affects their rewards too. The withdrawal security lock is currently seven days. This confirmation mechanism does not yet give validators full responsibility for producing and proving blocks.

Governance is a scoped protocol right. STRK or delegated voting power can approve network proposals, including major Starknet OS upgrades and minting parameters. The Foundation has delegated large treasury voting positions to selected delegates, so token voting is not the same as equal-person control. It also does not create corporate membership, equity, dividends, or a claim against StarkWare or the Starknet Foundation.

Upgrade authority follows three routes documented in 2026. Major releases require community voting, Security Council review and at least a seven-day freeze; minor releases still receive a vote but can omit Council involvement and use at least five days; an emergency can bypass token voting and be executed by the 12-member Council, requiring 75% approval under SNIP-25. The Council can protect liveness and security, but this is privileged multisignature power rather than ordinary STRK voting.

Ten billion STRK were created in May 2022 and minted on Ethereum on 2022-11-30. The allocation was 20.04% early contributors, 18.17% investors, 10.76% StarkWare, 12.93% grants/development partners, 9% provisions, 9% rebates, 10% strategic reserve, 8.10% Foundation treasury and 2% donations. Supply is not capped: community-set inflation mints staking and later block rewards. The revised contributor/investor schedule unlocked up to 64 million monthly from 2024-04-15 through 2025-03-15, then up to 127 million monthly through 2027-03-15.

Frequently asked questions

Are Starknet and StarkEx the same network?

No. Starknet is a shared general-purpose rollup for permissionless Cairo contract deployment. StarkEx is StarkWare’s tailored service for individual applications, each with its own operator and availability setup. STRK belongs to Starknet and does not govern StarkEx customers.

What can STRK holders actually vote on?

They can vote directly or delegate voting power for Starknet protocol proposals, including major OS upgrades and token-minting parameters. Proposal thresholds and the upgrade route matter; emergency Council action can bypass a token vote. Voting power is not ownership of StarkWare or the Foundation.

Does staking mean validators already sequence Starknet?

Not fully. In phase 2, validators run full nodes and attest assigned blocks to demonstrate liveness. The roadmap assigns block production, validation and proving in later phases, so staking rewards today should not be described as proof of completed sequencer decentralization.

Is STRK capped at ten billion?

No. Ten billion was the initial creation. Governance-approved minting supplies staking rewards and can later fund block rewards, so total and circulating supply can rise independently of scheduled unlocks.

Can the Security Council upgrade Starknet without holders?

In an emergency, yes: SNIP-25 gives the 12-member Council an immediate path with 75% approval and later reporting. Regular major and minor upgrades use community votes, with different Council and delay requirements.

Does Ethereum settlement remove every operator risk?

No. STARK verification rejects invalid proven state transitions and Ethereum stores settlement data, but sequencing can still censor or halt, proving can be unavailable, and privileged upgrades can change contract logic. These are separate trust surfaces.
